IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 199,265, dated January15, 1878; application filed October 15, 1877.

To all whom it may concern:

Be it known that I, IRA OOGSWELL, of the city of Chicago, county ofCook, and State of Illinois, have invented a certain new and usefulImprovement in Sash Fasteners and I do hereby declare that the followingis a full, clear, and exact description of the said invention, referencebeing had to the accompanying drawing, making a part of thisspecification, in which- Figure 1 is a front viewof the window, withfastener attached to lower sash; Fig. 2, a front view of the fastener;Fig. 3, a back view of the lever, and Fig. 4 shows a sectional view,taken on line 00 w of Fig. 2.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention consists in a friction-plate, hav ing a bearing-flangealong one edge and a locking-notch therein, and a circular opening toreceive an eccentric flange or hub on the operating-lever, and alocking-catch fixed to the window'stop to engage with said lockingnotch,whereby said plate may be forced against the window-stop with a positiveaction by said lever with such force as may be required to hold the sashor to lock it, all as hereinafter more fully described and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same.

A represents a friction-plate, having the locking-notch a. B representsalever or cam, and O is a stop. The frictionplate Ais made with alateral flange, having a smooth surface,

so that in the operation of the sash, with the fastener attached, itwill not mar or injure the sash-stop. A round hole is made in thefriction-plate, within which a circular flange or hub on the lever Bworks. The screw E is placed eccentric to the center of said hub andnearest the outer edge of the plate through the lever, thus aifordingsufiicient leverage to force the plate .A against the window-stop, andhold the sash firm at any point by pressing down the lever. The flangeof the plate A is provided with a notch, a, which is preferably placednear one end and when the sash is down the said notch in the fastenerlooks upon catch 0, which 'is fixed upon the window-stop, and therebythe window is securely locked, and can not be opened until the lever israised.

In the use of a fastener of this kind the sash is firmly held, and allrattle is prevented.

This sash-look can be made of iron, brass, or any metallic substance.

The ends of the friction-plate are beveled, so that in its movement thewood will not be marred.

'What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-- The sash-fastener described, consisting of theplate A, constructed with alocking-notch, a, in the friction-surface,and with a circular hole fitted to receive an eccentric flange or hub onthe lever B, which is pivoted upon and attached to the sash by a centerscrew, E, all constructed as described, and combined with a catch, 0,rigidly fixed to the window-stop, whereby the window-sash may be held orlocked without rattle or injury to the windowstop.

IRA OOGSWELL.
